12.6 Output Current Limit

Overload Operation
EC Titanium provides the following maximum permissible overload current:
• 150% Output current / 60 Seconds Maximum
• 175% Output current / 2.5 Seconds Maximum
Maximum continuous output current and maximum permissible overload time may be adjusted according to the following:
• PWM Switching Frequency Selected
• Low Output Frequency
• High Ambient Temperature
